My DH does the same thing. He hates making plans for anything, BUT when we get there he expects all the be planned out.
Last time we went it was for a Disney wedding, with the wedding you have different park ticket options, so he said to only get him a 2 day pass, cause he won't go to the parks that much, he'll hang out at the hotel and relax. The bride to be told me to get a bigger pass cause "you just know he'll change his mind" I didn't listen and got ordered the 2 days. When we got there he was all bent out of shape and I had to buy him passes when we got there. Then he wanted to know what day we were going to SciFi and when are we doing this park or that park.
